What is compressing an image?
  • Image compression is the process of reducing the file size of an image while maintaining its visual quality. This is done by removing or reducing the amount of data in the image file, while retaining the information that is important for the visual appearance of the image.
  • It's important to note that when compressing an image, it's a balance between the file size and the quality of the image. Compressing too much will result in a low-quality image, but compressing too little will result in a larger file size.
What are lossless and lossy compression?
  • Lossless compression: Lossless compression techniques retain all the original data of an image and can recreate the original image exactly. The file size of the image will be smaller, but the quality of the image will not be affected. Examples of lossless compression include PNG and GIF.
  • Lossy compression: Lossy compression techniques discard some of the data from the original image, resulting in a smaller file size but also a lower quality image. The degree of compression can be adjusted to balance file size and image quality. Examples of lossy compression include JPEG and WebP.
